This was a good read, thanks for sharing. I am also curious if anyone has any experience with this. Maybe this is a topic for a separate post, but I hadn't heard about a connection to too much dopamine before, so I did some (very basic) googling. Too much dopamine is "linked to being more competitive, aggressive and having poor impulse control. It can lead to conditions that include ADHD, binge eating, addiction and gambling" While I dont personally relate to aggressiveness or competitiveness, I have struggled with poor impulse control all my life. Is that something that other stutterers here relate too? It would be quite something to find out my impulsiveness is due to a neurological disorder rather than my upbringing..
